Dual Bootstrapped, 12 V MOSFET Driver with Output Disable ADP3120A The ADP3120A is a single Phase 12 V MOSFET gate drivers optimized to drive the gates of both high side and low side power MOSFETs in a synchronous buck converter. The high side and low side driver is capable of driving a 3000 pF load with a 45 ns propagation delay and a 25 ns transition time. With a wide operating voltage range, high or low side MOSFET gate drive voltage can be optimized for the be.
